UNITED STATES JOHN F. APPLEBY, OF MINNEAPOLIS,

P TENT @rrron,

MINNESOTA, ASSIGNOR TO THE MIN- NEAPOLIS HARVESTER WORKS, OF SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 314:,774, dated March31, 1885.

Application filed July 31, 1884. (Modell) To all whom it may concern:

Be it known that I, JOHN F. APPLEBY, of Minneapolis, Minnesota, haveinvented certain Improvements in Mechanism for Supporting and Adjustingthe Elevation of Harvester-Platforms, of which the following is aspecification.

My invention relates, first, to mechanism for enabling the driver of aharvester, while sitting in his seat, to raise and lower the platform;secondly, to mechanism by means of which the driver, while sitting inhis seat, can tilt the platform in either direction; and, thirdly, tothe construction of the grain-wheel, and to the 'instrumentality bymeans of which the grain end of the platform is supported upon thegrain-wheel.

The first part of my invention consists in supporting the drive-wheelend of the platform upon the rear of a quadrilateral jointed frame,mounted edgewise upon and extending rearward from the axle of thedrive-wheel. The rear end member of the quadrilateral frame is astandard affixed to and forming a part of the platform-frame or mainframe of the harvester. A brace adj ustably connected with the upperpart of the rear end member of the quadrilateral frame extends forwardand is-pivoted to the pole-socket at apoint which is forward of theaxial line of the drivewheel; The quadrilateral frame projects rearwardfrom the axle of the driv'e-wheel, and

supports the drivewheel end of the platform quadrilateral frame areprevented from tnrning"npon their horizontal pivotal connections bymeansof achain, one end of which may, forthe presentfib'e" considered asconnected with the rear lowencorner of said frame. This chain is thenceled diagonally across the-quadrilateralframe toa pulley pivoted upon theupperpart of'th e front end member of the quadrilateral fran e,whichmember is connected to a'n'd projectsradially from the hollow axleofthe" drivewheeh From this pulley the chainis led downward and fastcnedto a drum affixed to theinner'ehd of a ratchet-wheel.

shaft which extends through the hollow axle of the drive-wheel and isprovided upon its outer end with a ratchet-Wheel, which engages apivoted retainingpawl carried upon the hollow axle. By means of aradius-bar centered upon the hollow axle and provided with an impelling-pawl, also engaging the maneuwheel referred to, the driver is enabledto turn the drum'shaft, and thereby to wind up the chain upon the drum,the retaining-pawl serving to check the backward rotation of the Bymeans of a pawl lifter at tached to the radiusbar the driver is alsoenabled to lift the retaining-pawl out of engagement with theratchet-wheel.and to there by let the drum-shaft turn in the oppositedi- 'to be consequently lowered. Thelower member of the quadrilateralframe is loosely mount ed' at-its rear'end upon a hollow stud projectinghorizontally from a standard affixed to the platform-frame, the upperpart of which stand ard constitutes the rear end member of thequadrilateral frame. This stud is madehollow to admit the counter-shaft,by which power to operate the machine is transmitted from thedrive-wheel. p

In Letters Patent granted to me, serially numbered 305,039, Ihav'es'hown and described raising and lowering mechanism in which thereis embodied a quadrilateral frame,

the upper lateral member of which is hung at its rear end upon the axleof the drivewheel, so that the frame projects forward from the axle ofthe drive-wheel instead of backward therefrom, as in the present case.

The second feature of my present invention relates to the tilting of themachine, which I .efiect by means of mechanism connected with the rearend of the quadrilateral frame, and

operated by a bell-crank lever, the handle of which is conveniently nearthe drivers seat.

By the operationof this mechanism the members of the quadrilateral frameare made to turn npontheirpivotal connections, thusvaryingthe angles ofthe corners of thequadrilateral frame.

5 As the rear end member of the quadrilateral frame is the standardrigidly connected with the platform-frame, its angle of variation fromthe perpendicular is by this meansvaried, and the tilt of the platformis consequently varied 1o accordingly.

upon the end of a bar connected with the hollow axle of the drive wheel,and thus the weight of the driver is utilized to assist in.counterbalancing the weight of the platform suspended upon the rear endof the quadri-. lateral frame. The grain end of the platform rises andfalls simultaneously withthe drive; wheel. end thereof. This is effectedbypivoting, the grain end of theplatform upon one zo ad, of anup-and-down rocking.arm, the other ,end .of :which derivesitssupportfrom the grainrwheel. To. the upper side of; themiddle portion ofthisarm there .is affixed a chaim; which ,is led downward. and .under apulley ...g5.piv,otediin the grain end of the ,platform frame, andwhichis connected'by means of a longrlinkfi nder the platform v,with'another up chain, which is led upward around a pulley npon thedrivewheel endof' the pIatform-i frame -,and over a,pul ley carried bythe.rear

member, ,B, is a crank-arm rigidly affixed to Near its rear end the armB has affixed toit the latermeans of which power is transmitted from thedrive-wheel to drive the. operative parts of the machine. The front. endmember, B of the quadrilateral frameis ,an arm affixed to and projectingradiallyfroin the hollow shaft a, contained in the main axle a. Theupper lateral member, B is pivoted, at its forward end to; the front endmember, 13*, and at its rear end to the rear end member, 0.

The windlass for raising and lowering the machine consists of the drumJ, provided with the projecting spur j, upon which one end, is, oft'heWindlass-chain K is hooked. The drum J is affixed to the windlassshaft Jwhich extends through the hollow shaft a, and at its outer end hasaffixed to it the ratchet-wheel J the teeth 'of which are adapted to beengaged bya retaining-pawl, L, which is pivotedto an ear, of, affixed tothe outer endof the hollow shaft or. The pawl L is held against theperiphery of the ratehet-wheel J 2 by the spiral springL, but canbelifted out of engagement with the ratchet-wheel by means ofthefoot-lever Z, pivoted to the arm which supports the driversseat M, andconnected by the link Z to thetail end, L', of the pivoted pawl L.

The Windlass is operated by means of the pawl-lever N, which ;isfulcrurned upon the pivot N, upon which the retaining-pawl L rocks.There is pivoted to the pawl-lever N the hooked pawl a, the hooked endof which 1 is adapted to engagetheteeth of the ratchetlink atwith theimpelling-pawl n,

. lever upward toward the seat, andthus turns the windlass-shaftf in thedirection, indicated bythearrow and winds up the windlass-chain K uponthe drum J. 'The Windlass-chain K is ledupward from the spur j and overthe guide-pulley k, which is pivoted to the side of the front member, 13of the quadrilateral frame near the upper end of the said memher. 1"From the guidepuley 7c the Windlass: chain-is led downward across thequadrilateral frameiand at itseud 7c is connected to the lower corner,Z), of the oscillating plate I). By'means of this connection thesnspensory effect of the windlasschaiu is exerted upon, the rear end ofthe quadrilateral'frame. The

chain is prevented from unwinding from the drum by the action of theretaining-pawl L, pivotally supported upon the car a, affixed to thehollow shaft to, with which the front end member, B of the frame isrigidly connected.

It follows, therefore, that upon winding up the Windlass-chain K uponthe drum J the lower rear corner of the quadrilateral frame is drawntoward the front upper corner there of. This is illustrated in Figs. 2and 3, in which 'the latter shows the elevating effect produced byturningthe Windlass-drum J from the position in which it is representedin Fig.

2 to the position in which it is shown in Fig;

3, and thereby winding up the chain K upon it.

The raising and lowering of the grain end of the platform simultaneouslywith the drivewheel end is effected by means of the chain 0, which ishung upon the inner end of the windlass-shaft J and is then led backwardover a guide-pulley, O, pivoted to the side of the oscillating plate b,thence downward around a pulley, O", pivoted to the gear-frame, thenceto the drive-wheel end of along link, 0 which extends under theplatform, and at its oppo site end is connected with a chain, 0, whichis led under theguide-pulley O pivoted to the cross-bar F, thence upwardover the curved face of the flange 9, cast upon the side of the rockingarm 9. The end 0 of the chain O, is hooked around the bolt 9 inserted inthe ear g projecting upward from the npperpart of the curved face of theflange g, the curvature of which is concentric with the pivot F, uponwhich the arm 9 rocks.

On reference to Figs. 2 and 3 itwill be seen that the effect ofelevatingthe quadrilateral frame is to increase the distance between theWindlass-shaft J and the guide-pulley O,.piv-: oted to the rocking plateI). This increase .in the distance of the pulley 0' from the center ofthe'd'rive-wheel has the effect of taking up the chain O'an'd haulingthe lower end of the chain 0 toward the drive-wheel. As the pul-l ley Orests in the bight of the chain 0 it is by this means raised-upwardtoward the bolt 9, to which the end 0 of the chain 0* is hooked, whichhas the effect of raising the cross-bar F at the grain end of theplatform, whichmay by this means be raised from the position in whichitis represented in Fig. 8 to the position in which itis represented inFig. 9.

To lower the platform, the drivenfirst raises the pawl-lever N, andthen, havingdisengaged ICC the retainingpawl L by pressing forward the ifoot-lever Z,lowers the pawl-lever N, and thus allows the drum J to turnin the directionopposite to that indicated by the curved arrow, therebyunwinding the chain K from the drum and lowering the rear end of thequadrilateral the platform is suspended it will be seen that in tiltingit rocks upon the axis afforded by the hollow crank-pin O, and that thetilting of the platformin either direction involves a variation in theangle from the perpendicular of thestaudard O, which constitutes therear end member of the quadrilateral frame. The upper end of thestandard is practically connected with the pole-socket H by reason of.

the connection of the rear end of the link H V v with the upper cornerof the rocking plate b.

The weight of the forwardly-projecting pole, therefore, tends to rockthe upper end of the standard 0 forward.

In. considering the tilting operation of the platform the forward end ofthe pole may be regarded as a fixed fulcrum, and it will be observedthat by rocking the rocking plate b,to which. the rear end of the link His pivoted, the distance between the upper end of the standard 0 and thepole-socket H is varied,

and thereby the deviation from the perpendicular of the standard 0 iscorrespondingly varied. a

. The rocking of the rocking plate b for the i purpose of varying thetilt of the machine is effected by means of the bell-crank lever P, thehandle l? of which is within convenient distance of the drivers seat.The short arm P? of this bell-crank lever is pivoted to an ear,

b projecting radially outward from the edge of the rocking plate b, andat its elbow P the bell-crank lever is pivoted to the upper end of aneye-bar, P, the lower end of which is pivoted to an ear projectingforward from the bed-plate D.

The disengagement of the retaining-pawl b, pivoted in the rocking plateb, from the rack b", formed in the edge of the standard 0, is effectedby means of the bell-crank lever 19, pivoted to the elbow of thebell-crank lever P,

and'connected by the link 1) with the hand" lever pivoted to thebell-crank lever P, in

close proximity to the handle 1?.

Thearm p of the bell-crank lever p is pro- .'.vided with alaterally-projecting pm, which engages aYsuitabl'y'curved slot formed inthe armpflaffixed to and projecting radially-from the shaft insertedthrough the rocking plate b, to, which the retaining-pawl b is affixed.

.When the bell-crank lever'P is thrown forward and downward,the machineis tilted forward and downward, as indicated by theinclined position'ofthe bed-plate D, (shown in section in Fig. 4;) but by throwing the bellcrank lever upward into the position in which 'it is" represented inFig. 5 the distance between the upper end, U of the standard 0 and thepole-socket H is increased,.and the angle of the upper. lateral member,B of the -s. quadrila'teral' frame has become less obtuse thanit waswhen the parts were in the position in which they are represented inFig. 4, thus slightly reversing the tilt of the machine,- as indicatedby the position in which the section of the bed-frame D is representedin Fig. 5. v

..In turning the rocking plate b down from the position in which it isrepresented in Fig. 4,1;0 that in which it is shown in Fig. 5 thedistance between the lower eornerybfl of the plate b and theguide-pulley It is increased,

thus making requisite a greater length of chain,

to extend from the guide-pulley 7cto the corner b of the rocking plateb. This downward movement of the plate b has therefore some} elevatingeffect upon the rear end of the quadrilateral frame if the chain K is'not unwound. This effect, however, is H from the Windlass.

lessened by the fact that-the radius at which acted by letting theWindlass-chain K unwind from the drum sufficiently to lower th platformthe required distance.

. The drivers seat M is supported uponthe.

upper end of the inclined arm M, which is" secured to the forward end ofthe arm M rigidly connected with the front end-member, B

Thus the weight of the quadrilateral frame. of the driver'is utilized toassist incounterbalancing the weight of themachine suspended upon therear end of the frame. I I

The object of the retaining-pawl b and the rack formed in the edge ofthe standard Q is to hold the rocking plate b in any position to whichit may have been adjusted, so that the quadrilateraljarring of theparts, when the machine is at work, will not change the tilt of themachine.-;

The up-and-down rocking arm g iscOmposed of two members, the adjoiningends of which are pivoted together by the bolt e".

The adjoining ends of the members. are bent laterally, sothat'their.pivotal connectionzis IIO brought within the rim G of the grain-wheel-QThe spokes G of thefgrain-wheel are curvedf outwardly from therim G? tothe hub Gt thus affording clearance forthejointed connection of the twomembers of the rocking arm GdllIq ing the rotation of the grain-wheel;The rear membeng, of the jointed armis'afiixed to the I the grain-wheelis permitted to swing lateraxle of the grain-wheel.
